I think Islam is really a viable modern social, political, legal, scientific, metaphysical institution. Let's looks BEYOND what we see on TV today for a minute. Islam in the past really dominated everything and was an extremely dynamic and a positive change that changed the face of the world especially in the pagan Arabia. Same things were being practiced in Arabia 1300 years ago that are being practiced in the HINDU region/society today, IE female infanticide, slavery, etc. Islam put an end to it and the RELIGION actually was the first and ONLY religion to have women's rights! (Hard to believe it because of what's going on today! It is too bad that it has been hijacked by some lunatics but I believe that time has come to an end for the lunatics and the REAL "infidels" who happen to be the terrorists who have hijacked a great religion). Islam Dominated pretty much everything up until recently, such as Algebra, Physics, Sciences, Astronomy, Medicine, Architecture. I believe the decline of the Religion of Islam began when people no longer practiced the true religion anymore which has led to these terrorists hijacking it as well.
I believe it will be ONLY become a viable modern social, political, legal, scientific, metaphysical institution WHEN the majority of Muslims, thereal Muslims, the moderates, take their religion back from the "TRUE INFIDELS" who have hijacked it and commit crimes against humanity in the name of this religion.
